2W isolated DC-DC converter Fixed input voltage, unregulated single or dual output
Description
A_D-2WR2 &B_D-series is designed for use in distributed power supply systems and especiall suitable in applications such as pure digital circuits,low frequency analog circuits,relay-driven circuits and data switching circuits,where:
1. The voltage of the input power supply is relatively stable with a variation of ±10% Vin or less;
2. Aninputtooutputisolationvoltageofupto1500VDCisnecessary;
3. The requirement for a tight output regulation is not as strict.
